"John Alanis and the Alanis Air crew were a pleasure to work with. Our 40 year old furnace needed replacement. We called John at Alanis Air and he responded immediately. He came to the house, diagnosed the situation and recommended a heat pump to take advantage of our solar panels. John and his crew showed up the next Monday and completed the job in two days. John and his crew were very knowledgeable and efficient. They covered all furniture and floors and cleaned up after completion of the job. We were very satisfied with the price and the work was exceptional. I would recommend Alanis Air to anyone that needed HVAC work."

"I recently had a new HVAC system installed by Aireserv, and I couldn't be more pleased with the results. From the beginning, the team was professional, courteous, and informative. They arrived on time and were very thorough in explaining the detailed installation plan, the features of the new system, and how to operate it. The installation went smoothly, and the technicians cleaned the area while working. Once the system was installed, they ran tests to ensure everything was working perfectly and took the time to answer all of my questions. The new HVAC system has been a game-changer in terms of performance. It heats and cools my home more efficiently than my previous unit, and I've noticed a significant improvement in comfort and air quality. The system runs quietly and maintains an even temperature throughout my home. I also appreciate the energy savings I'm already seeing.

"What: NOT Plumbing. Electrical wiring for/and installation of flood lights above garage door, side walkway to backyard, and backyard. Also installed porch light. Pros: On time, courteous Comments: Backyard floodlight was on all day & all night and on the same electrical source of the lights in the laundry room light and side walkway to backyard. The only way to turn it off was to turn off the electrical switch in the box, which turned off all 3 lights mentioned above. The flood lights were supposed to be on, with a timer, only during dark hours, but either it was on all night because they tied it to the laundry & walkway "wire" or electrical switch, OR they didn't put it on timer, or some other reason. They sent another team out to fix the issue within the next few weeks. Recommendation: Buy your own light fixture, inform YOU want to pick and have them install. Otherwise, they go with their own vendor and the alternative did not look anything like the style we wanted."

Heat pumps rely on evaporation and condensation processes. The unit transfers heat through the system via a compressed refrigerant. The compressor within the pump circulates the refrigerant through two coils. The first coil evaporates the refrigerant and absorbs warmth from the air. The refrigerant then passes to the second coil, where it condenses, and the unit releases the absorbed heat.
A well-installed and well-maintained heat pump lasts an average of 12 to 20 years. Routine filter changes, annual tune‑ups, and prompt repairs help the equipment reach the upper end of that range, while skipped maintenance or poor installation can shorten its life and raise long‑term costs. Ask your heat pump installation pro for maintenance recommendations so you can get the maximum benefit from your unit.
Heat pumps are most effective in regions where winter lows remain above approximately 40°F. Efficiency starts to drop below that point and falls off sharply near 25°F. If you live in a colder area, look for a model with a high Heating Seasonal Performance Factor (HSPF) and plan on supplemental heat during deep freezes to keep energy use in check.
The biggest drawbacks are the upfront cost and poor cold-weather performance. Installation can require electrical upgrades or duct changes, and once temperatures fall well below freezing, the unit may need help from a furnace or electric resistance coils. Factor in those add‑ons, along with routine maintenance, when you weigh the long‑term savings against the initial investment.
